SELF-REGISTERING GAGE.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed February 5, 1907. Serial No. 355,827.

To all whom it may concern:

Be it known that I, MARSHALL S. SHAP- LEIGH, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented new and useful Improvements in Self Registering Gages, of which the following is a specification.

The object of my invention is the production of a self-registering gage which shall be simple in construction and comparatively cheap in first cost; so designed that it will not easily become deranged, and can be used to quickly and accurately measure the diameter of wire and the thickness of other objects; and which shall be of such a size that it can be attached to a watch chain or a key ring, or can be carried in a vest pocket.

The invention consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.

The accompanying drawings illustrate an, example of the physical embodiment of the invention constructed according to the best mode I have so far devised for the practical application of the principle.

Figure 1 is a face view of the gage enlarged to more clearly illustrate the design. Fig. 2 is an'edge view in section, the section being talgan on line 22, and looking towards the ri t.

Referring to the several figures of the drawing, the numeral 1 designates a flat piece of metal constituting the base of the gage, the same being cut to the shape shown by means of dies or otherwise; 2, a projecting curved finger; 3, the convex ed e surface of the finger; 4, a hole for the attac ment of the gage to a watch chain, key ring, or otherwise; 5, a curved scale graduated to inches and fractions thereof, or to centimeters, or

other convenient linear measures; 6, a hole to recelve a journal or eyelet; 7, a pivoted curved finger and index made in one piece as shown; 8, the curved edge surface of the finger corresponding to the surface 3 of the finger 2 in connection with the base; 9, the index or pointer which travels along the scale; 10, a hole in the movable finger and 11 is an eyelet passed through the holes 6 and 10 and upset.

The end of the finger 7 is offset from the plane of the index or pointer so it will lie when pivoted in the same plane as the finger 2. If desired the said finger 2 ma also be ofiset from the plane of the base. he eyelet is shown of a large diameter so as to afford a large bearing area whereby the wear will not be excessive. By the use of a small journal the finger and index would be liable to displacement and the device thus become deranged. The use of the gage is obvious and need not be set forth.

What I claim is:

A self registering gage comprising a plain base plate having a scale upon the face adj acent one end thereof, the opposite end being fashioned into a projecting finger, a pivoted finger and index, and an eyelet passed through the base plate and the central portion of the pivoted finger and index; one of the fingers being ofiset so both fingers will lie in the same plane, and the fingers respectively provided with curved surfaces 3 and 8, whereby a wire may easily be inserted and withdrawn from between the fingers.

In testimony whereof I affix my signature in presence of two witnesses.

MARSHALL S. SHAPLEIGH.
